Astronomers Discover Unusual Galaxy That Should Not Exist
Astronomers Discover , Unusual Galaxy , That Should Not Exist.
'Newsweek' reports that NASA's
James Webb Telescope has discovered
a new galaxy that shouldn't exist.
.
The dwarf galaxy, referred to as PEARLSDG,
was spotted in an area of space where
astronomers were not expecting to find anything.
A new paper in the 'Astrophysical Journal Letters'
details the strange properties of PEARLSDG,
chiefly how it appears to not be forming new stars.
Normally, dwarf galaxies
orbit larger galaxies, which
influences their formation.
.
Our Milky Way is orbited by
about 20 dwarf galaxies, like the Small
Magellanic Cloud and Triangulum II.
PEARLSDG appears to not be
interacting with any nearby galaxies,
while also not forming any new stars.
Scientists now believe PEARLSDG
is a rare isolated quiescent galaxy.
.
These types of isolated quiescent
dwarf galaxies haven't really been seen
before except for relatively few cases, Tim Carleton, paper co-author and an assistant research
scientist at Arizona State University, via 'Newsweek'.
They are not really expected to
exist given our current understanding
of galaxy evolution, so the fact that we
see this object helps us improve our
theories for galaxy formation, Tim Carleton, paper co-author and an assistant research
scientist at Arizona State University, via 'Newsweek'.
Generally, dwarf galaxies that
are out there by themselves are
continuing to form new stars, Tim Carleton, paper co-author and an assistant research
scientist at Arizona State University, via 'Newsweek'.
'Newsweek' reports that the findings suggest that
astronomers have much more to learn about dwarf
galaxies, including how they evolve over time.
NASA Reestablishes , Connection With Distant , Voyager 1 Space Probe.
The news comes after engineers at
the agency worked for months
attempting to fix the 46-year-old probe.
In December, NASA's Jet Propulsion Laboratory (JPL)
said that the probe, now a staggering 15 billion miles
away from Earth, was transmitting gibberish code. .
On April 23, the JPL announced that
the team was once again receiving
usable data from the spacecraft.
Currently, the probe is only
transmitting data regarding the status
of the ship's engineering systems.
The next step is to enable
the spacecraft to begin
returning science data again, JPL statement, via 'The Guardian'.
'The Guardian' reports that Voyager 1 has been in
operation for nearly half a century after launching
in 1977 with the goal of studying Jupiter and Saturn.
In August of 2012, Voyager crossed into
interstellar space, becoming the first
human-made object to leave the solar system.
The probe is currently traveling at a staggering
36,800 miles per hour through space.
NASA plans to collect data from the two
Voyager spacecraft for a few more years,
but the space agency expects to lose
contact with the probes within the next decade

NASA has unveiled striking images capturing the extensive flooding in the UAE following the recent torrential rainfall. Describing it as a "slow-moving storm," NASA highlighted the unprecedented deluge that inundated the Gulf states, surpassing a year's worth of rainfall in some regions. According to the UAE's meteorological department, the country received a staggering 6.04 billion cubic metres of rain last week, nearly equivalent to its annual precipitation of 6.7 billion cubic metres. This remarkable event underscores the magnitude of the weather phenomenon that swept across the region.

Two Telangana students, Nivesh Mukka and Goutham Kumar Parsi, aged 19, tragically perished in a road accident in Arizona, USA. Both studying computer science engineering at Arizona State University, they were returning home when their vehicle collided head-on with another car. The families urge Indian government assistance to repatriate their bodies. The incident underscores safety concerns for Indian students abroad.

Astronomers May Have Solved, the Mystery Surrounding , Blue Supergiant Stars.
'Newsweek' reports that astronomers now believe
that some of the brightest and hottest stars in existence
may be the result of collisions between two other stars.
Scientists have long sought to determine
how these intensely bright stars,
known as blue supergiants, are formed. .
According to a new paper published by
'The Astrophysical Journal Letters,' scientists
suggest that blue supergiants are the result
of two binary stars merging into one.
Blue supergiants, which are about 16 to 40
times the mass of our sun, are some of
the most massive stars in the universe. .
Their intensely hot surface temperatures
are often two to five times hotter than our
sun and over 10,000 times more luminous.
'Newsweek' reports that the latest research
looked at 59 early B-Type blue supergiant
stars in the Large Magellanic Cloud,
a satellite galaxy of our own Milky Way galaxy. .
We simulated the mergers
of evolved giant stars with
their smaller stellar companions
over a wide range of parameters,
taking into account the interaction
and mixing of the two stars
during the merger, Athira Menon, study author and an astrophysicist at the Instituto
de Astrofísica de Canarias (IAC) in Spain, via 'Newsweek'.
The newly-born stars
live as blue supergiants
throughout the second
longest phase of a star's life,
when it burns helium in its core, Athira Menon, study author and an astrophysicist at the Instituto
de Astrofísica de Canarias (IAC) in Spain, via 'Newsweek'.
The results obtained explain
why blue supergiants are found
in the so-called 'evolutionary gap'
from classical stellar physics,
a phase of their evolution where
we would not expect to find stars, Artemio Herrero, study co-author and a researcher at the Instituto
de Astrofísica de Canarias (IAC) in Spain, via 'Newsweek'.
The team reportedly hopes to continue its
investigation into the role that merging stars
could play in the formation of galaxies, as well as how
blue supergiants form neutron stars or black holes. .
